Drug treatment improves learning in mice with Down syndrome symptoms, Stanford/Packard study shows

...udent in Garner’s laboratory. Fernandez found that affected mice were significantly better able to identify novel objects and navigate a maze ­ tasks that simulate difficulties faced by children and adults with Down syndrome ­ after being fed 17 daily doses of milk containing a compound called pentylenetetraz...

Coated nanoparticles solve sticky drug-delivery problem

...anomedicines that can be delivered directly to the affected areas." To get its particles past the mucus, Hanes' team studied an unlikely model: viruses. Earlier research led by Richard Cone, a professor in the Department of Biophysics at Johns Hopkins, had established that some viruses are able to make the...

Colour sensor breath test can detect lung cancer

...of those with lung cancer. The results were not affected by age, gender, or stage of disease. Other approaches to breath testing have been used, say the authors. This includes gas chromatography and mass spectrometry, which requires a great deal of expertise to use and is very expensive. As cancer is...

New insights into autoimmunity and depression

...elp determine whether these pathways are similarly affected in humans. "The relevance of the results to the involvement of the central nervous system in SLE is another intriguing aspect of the present study," notes its leading author, Yehuda Shoenfeld, M.D., while emphasizing the need for further investiga...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

...nsport of terrestrial material to all areas of the affected reefs and reef waters. Managers of the GBR have long been examining the effects of run-off of sediments, including pesticides, herbicides and fertilizers, on the reef corals. The images challenge the traditional school of hydrological modellin...

Clues to gene expression in cystic fibrosis will guide research

...nstitutions studying how the antibiotic gentamicin affected CF patients with a stop mutation. The team used a dual reporter gene assay first in vitro and then in CF patients. The study found that a small subgroup of patients with the Y122X mutation, found mainly in inhabitants of Reunion island, responded to ...

New fMRI technology making brain tumor surgery safer

... The Neuroscience Institute. “It has significantly affected how neurosurgeons plan to do neurosurgery and how much tumor they can remove while still avoiding critical areas of brain function.? Said Christopher McPherson, M.D., a neurosurgeon with The Neuroscience Institute: “It’s easier and safer for the pa...

Stress hormones may play new role in speeding up cancer growth

...Glaser and Yang wanted to see how these same drugs affected these tumor cells. They added propanol, a beta-blocker, to the tumor cells and then exposed them to both norepinepherine and epinephrine. With the drug present, the levels of MMP-2, MMP-9 and VEGF didn't increase. "This suggests a new approach to ...

By 2048 all current fish, seafood species projected to collapse

...rotected areas -- reserves and fishery closures -- affected the recovery of services. The researchers were surprised to find very similar relationships between biodiversity change and ecosystem services at scales ranging from small square-meter plots to entire ocean basins, Worm said. "This suggests that sm...

UCSF study will test new vaginal microbicide for herpes and HIV

... HIV/AIDS diagnoses. Women of color are especially affected by HIV infection and AIDS. In 2002, the most recent year for which data are available, HIV infection was the leading cause of death for African American women aged 25 to 34 years. It was the third leading cause of death for African American women age...

How did bilaterally symmetric flowers evolve from radially symmetric ones?

...anada, Spain) explored how different flower shapes affected plant fitness in natural populations of Erysimum mediohispanicum, a Mediterranean herb. Their findings will be published in the October issue of The American Naturalist. The researchers found that plants bearing bilaterally symmetrical flowers were...

Evolution of influenza A virus

...nfluenza virus diversity and evolution is strongly affected by chance events, such as reassortment between strains coinfecting a host or the introduction of a particular variant from elsewhere. These factors make predicting future patterns of influenza virus evolution more difficult, as vaccine strain selecti...

Harvard scientists identify compounds that stimulate stem cell growth in the brain

...h may one day lead to restored function for people affected by Parkinson's disease, strokes, multiple sclerosis, and a wide range of neurological disorders. These findings, which appear in the September 2006 issue of The FASEB Journal, provide important clues as to which compounds may be responsible for causi...

Researchers seek to design first treatment for neuroAIDS

.... Thus, MLK inhibitors could conceivably shut down affected immune cells before they trigger inflammation and prevent cell suicide. The new grant is a partnership between the University of Rochester Medical Center and the Center for Neurovirology and Neurodegenerative Disorders (CNND) at the University of Ne...
